Abstract There are large differences of Moho local features in the southern area of the north-south earthquake belt. This article applies the Parker-Oldenburgiterative inversionmethod with constant density and variable density models on the southern area of the north-south earthquake belt. The results indicate that the variable density model’s reverse results are more reliable, and that the two reverse results’ general morphological characteristics are consistent. Between the differences of theinversion results, the maximum difference is less than 2 km, and the results of the variable density model are much deeper. The mantle uplift in Panzhihua and the mantle concave in Dongchuan are extremely significant, indicating that deep geologic processes have important influence on regional tectonic earthquake activities.
